So very close to getting #gnuradio and #aldec #riviera-pro to work together. Now it's just a matter of libraries I think. Seems like maybe they wrote things for a different version of GNU Radio. Of course this is just the EXAMPLE. Getting it to work with my own material is probably another question entirely.

Well appears as if there's no concept of time in #gnuradio. Everything is sample based. It's understandable but means the first helper module I think I will need to write is a sample counter though to provide other modules with a concept of time.

@Tathar Well, for avionics test, I do signal receipt and correlation and demodulation, then the other side modulation and transmission in #VHDL. However that's not what's making me walk through gnuradio. Apparently #Aldec has a block that lets you use #gnuradio in co-simulation with #Riviera-PRO. If I have an easier to work with signal generation or signal analysis tool, it would aid verification.
I've written signal toolbox stuff in VHDL for simulation, but I'll be honest, it's a pain in the ass to work with: tedious to construct and a pain in the ass to modify (depending on what you want.). There's a possibility gnuradio is easier (though also a possibility it is not. I've not yet got through a tutorial that actually gave me a sense of how the tool deals with time. I think it probably doesn't which means if I need a particular timing I will be sample counting and it'll make it anchored to sample rate when it'd just be nicer to wait X microseconds and then modulate.)

Picked up some #whistlers from last night's #thunderstorms!
I thought I heard them last spring (storm season in the Southern Plains) but also caught their #vlf spectra last night.Spectra are produced with #gnuradio as "waterfall charts" : time on the y axis (most recent at bottom) and freq on the x axis.
Circuit was just a whip antenna with FET front end plus some amplification, and a low pass filter to remove broadcast radio, and a sharp high pass filter to remove power hum & harmonics.

The annual @gnuradio conference just started!
Turing laureate Jack Dongarra is the first keynote speaker! If you ever used LAPACK, BLAS (and you did – whether you know it or not), read the top500 supercomputer list, or are just all for sharing numerical libraries – you want to head to the streams on https://grcon.stream

Problem reproducing a bug:
Does anyone have a #MacOS machine with #gnuradio installed through standard ways?
Does your audio source work on the first try, i.e., does it just work or at least ask for permission to use the microphone?

The #GRCon #CTF is under way, and runs until Thursday at 16:00 EDT (20:00 UTC). There's something for everyone; no prior #GNURadio experience necessary. https://ctf-2024.gnuradio.org/ flag{go0d_lucK!}

Pretty happy that Dan Boschen of DSP.SE and DSPrelated fame is doing workshops at @gnuradio Conference 2024 (#GRCon'24) in September (16.–20.):
https://events.gnuradio.org/event/24/page/147-keynote-speakers
If you've ever gotten an answer on https://dsp.stackexchange.com, you'll know that the figures will be excellent and the explanations to match that. We'll be learning things on digital filter design and control loop development. Workshop space is limited, but no extra cost to the registration for GRCon in-person participation.
